Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X100S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X100S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø20mm bore and 100mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 132 N each way at 0.5 MPa. Fixed rubber bumper.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X100S
The AirTAC MBLD20X100S is a double-acting, double-rod aluminum mini cylinder engineered for compact setups needing symmetrical motion. A single piston drives an 8mm carbon-steel rod out of both end covers, yielding identical extend and retract forces of 132N at 0.5 MPa. The built-in magnet (the S code) enables position detection via CMSG reed or DMSG/EMSG electronic switches. With a 100mm stroke, the overall length equals the base body length plus twice the stroke, so you must leave rear-rod clearance for the protruding shaft.
Unlike single-rod variants, this twin-rod layout provides dual-side guidance that resists torsional rotation, letting you mount a workpiece on one end and a cam or position flag on the other. The riveted rolling-packed aluminum barrel and grease-retaining piston seal keep the body light for tight spaces. Impact is absorbed by a fixed rubber bumper, not an adjustable air cushion.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X100S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X100S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø20 mm |
| Stroke | 100 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 300 mm |
Double-rod overall length = A + 2 × stroke — leave clearance for the rear rod. MBLD/MBLCD mounting is Basic / FA / LB only (no SDB, no back-cover code). Thread options: PT / G / NPT.
Output Force (Ø20mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 132 N |
| 0.7 MPa | 185 N |
| Max (@1.0 MPa) | 27 kgf |
A rod on both piston faces makes the annulus area equal, so extend and retract force (and speed) are the same. Actual usable force is lower due to friction.

Where the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X100S Is Used
PCB Edge Routing
Drives a light routing spindle on one rod end while the opposite end carries a limit flag, using the 132N equal force to maintain steady feed rates during board depaneling.
Chip Test Socket
Applies 185N at 0.7 MPa to seat ICs into a test socket with twin-rod anti-rotation guidance, preventing binding across the 100mm travel.
Label Applicator Cam
Uses the rear protruding rod to actuate a mechanical cam for label timing, keeping the front 8mm rod dedicated to precise label contact.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X100S the Right Cylinder?
If 132N both ways is insufficient, step up to the MBLD25X100S, which provides 206N at 0.5 MPa. If you need less force and an even smaller footprint, note that 20mm is the smallest available bore in this series. For applications requiring softer end-of-stroke deceleration, choose the MBLCD variant which features adjustable air cushions instead of this fixed rubber bumper.
Mounting is limited to Basic, FA flange, or LB foot brackets; there is no back-cover or SDB pivot option for the double-rod type. The PT tapered port thread is standard. To replace this unit, match the 20mm bore, 100mm stroke, PT thread, and the -S magnet. Note that a plain MBLD does not hold position without live air; the rod drifts, so use an external lock for holding.
Quick checklist
- ✓ Equal force both ways at your pressure
- ✓ Rear-rod clearance (length = A + 2 × stroke)
- ✓ Mounting: Basic / FA / LB only
- ✓ Magnet (S) for sensors?
- ✓ Side load — add a guide on long strokes
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Leave clearance for the rear rod (length = A + 2 × stroke).
- check Avoid side load; add an external guide on long strokes.
- check Mounting: Basic / FA flange / LB foot (no SDB, no back-cover code).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X100S FAQ
Because a rod occupies both piston sides, the annulus area is identical in both directions. The force is 132N at 0.5 MPa and 185N at 0.7 MPa, with a theoretical maximum of 27 kgf at 1.0 MPa.
The twin rods provide equal force and speed both ways while improving load guidance against rotation. The -S suffix means a magnet is built in for CMSG reed or DMSG/EMSG solid-state sensors; without S, no sensor can be fitted.
